(8) I2C timing
(AVCC
= VCC = 3.3 V ± 0.3 V, VSS = AVSS = 0.0 V, TA = 40 °C to + 85 °C)
*1 : fCP is internal operation clock frequency. Refer to “ (1) Clock timing”.
*2 : R, C : Pull-up resistor and load capacitor of the SCL and SDA lines.
*3 : The maximum tHDDAT only has to be met if the device does not stretch the “L” width (tLOW) of the SCL signal.
*4 : Refer to “
Note of SDA and SCL set-up time”.
